Rapeseed matrix seedling transplanting machine pneumatic clamping seedling separation device

Abstract

The invention discloses a pneumatic clamping type seedling-picking device for a rape matrix block seedling transplanter, comprising a seedling-separating device and a seedling-picking device; the seedling-separating device includes an adjustable seedling-separating cylinder, a seedling-separating pull rod, The clamping device on the top and the seedling picking platform device installed at the end of the seedling pulling rod; the seedling picking device includes an outer hinged rotating arm and an inner hinged rotating arm, a seedling picking drive cylinder, a parallel finger cylinder and two seedling picking splints. The seedling separation device adopts double-sided seedling separation splints to clamp seedlings, and the two sides of the seedling separation splints are respectively in contact with the side of the matrix block seedlings. When the seedlings are separated, the extrusion force on the matrix block is less than its yield force, which realizes non-destructive separation of rapeseed matrix seedlings. seedlings; the seedling picking device adopts double-sided symmetrical seedling picking splints to clamp and take seedlings, and the seedling picking splints move toward each other on both sides of the matrix block to clamp the matrix block, and the clamping part does not touch the root system of the rapeseed matrix seedlings; The entire row of substrate block seedlings is continuously transported to separate individual plants, and the seedlings are taken and planted synchronously, which reduces the labor intensity of seedling separation and seedling picking.

Description

Technical field [0001] The present invention belongs to the field of crop transplanting technology, and in particular, the pneumatic clamping type deposit membrane device of rapebel material block seedlings is specifically involved. Background technique [0002] Rape mechanized transplanting can make full use of effective growth during winter, forming a large seedlings before winter, is conducive to the growth of the masculine, and can make up for the lack of long-term growth in the field to increase the production of rapeseeds. The mechanized transplanting of rapeseed is divided into semifinals, sends a seedlings, mining seedlings, and planting, where the seedlings are the key links in the field of rape mechanization transplanting. [0003] The existing rapeseed machinery is mostly a general-purpose transplanting machine, and its division seedling device is generally mechanical, mainly for the acupolar seedlings and gentlem seedlings. When the seedlings are separated, the seedli...

AI Technical Summary

Problems solved by technology

[0004] At present, the domestic research on the mechanized transplanting of rapeseed seedlings is in its infancy, and there is no established seedling-picking device for the transplanting machine of the matrix seedlings; it is limited to the difference between the shape and physical characteristics of the matrix seedlings and pot seedlings and plug-in trays. There are certain differences in seedlings, so the general-purpose transplanting machine sorting device cannot meet the requirements of effective and non-destructive sorting of rape substrate seedlings
